SPECIFICATION forming part of Letters Patent No. 493,096, dated March 7,1893.

Application filed June 22, 1892. Serial No. 437,599. (No Inodel .To @ZZwhom it may concern:

Be it known that'I, LOUIS G. KREGEL, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inFastenings for Hermetic Burial- Caskets, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

This is a device for tightly closing the'metal cover to the metal bodyof the case in a way that is at once silent, expeditious, easy andeffectual, as will be hereinafter fully described and the novel featuresdetermined by the claims.

Figure I is a detail side elevation showing sufficient of a burialcasket to illustrate the invention, and Fig. II is a detail top view ofthe same. Fig. III is a detail transverse section taken at III-III, Fig.I the head of the fastener being shown in elevation. Fig. IV is a detaillongitudinal section taken at IV- IV, Fig. II, parts being in elevation.Fig. V is a detail elevation showing the locking screw or stud upon theupper edge or rim of the body. Fig. VI is a similar view with the rim ofthe body in section to show the screw.

l is the body of the casketin which no novelty is claimed per se.

3 is a sealing strip or gasket of rubber extending around upon the topof the rim 2 of the body, so that'when the edge or flange 4a of the lidor cover 4 is forced down upon the sealing strip or gasket 3 the casketis sealed hermetically.

The invention relates to the means for forcing and holding the coverdown as before stated and this will now be described.

5 are studs which are firmly fixed in the rim 2 of the body projectingupward vertically from .the rim. These studs are preferably screwthreaded at the lower part for engagement in the rim 2, and have anenlargement or collar 5a whose lower end rests on the top of the rubbergasket and thus holds it in place. I have used for the studs wood screwshaving the usual round topped head 5b which head forms an essentialfeature of the fastening. When a wood screw is used the collar 5u isfixed to it in any suitable manner. I have cast the collar of whitemetal upon the shank of the screw so that it adheres fast to the shank,but it may be attached in any way. The iiange 4a of the casket top orlid 4 has a series of Vertical screw threaded sockets 6 equidistant fromthe edge and at short intervals from each other. In these sockets turnthe tubular screws or nuts 7 which are adapted to fit over the studs'and turn thereon. The nuts 7 have arms 8 by which they may be turned intheir screw sockets.

9 is a latch swinging horizontally on the pivot. l0 whose head 10a formsthe knob by which the nut 7 is. turned. The latch has .a notch or recess1l adapted to embrace it is in the position seen at B. When the latch isin the position seen at A the cover 4 may be removed from the body 1 orplaced thereon. The latch has a thumb piece 9a by which it may be turnedon its pivot.

The operation of the device is as follows: The cover is placed on thebody when the nut and latch are in the position seen at A. The latch isnext turned so as to engage the stud and then the nut is turned into theposition shown at B or a sufficient distance to force the lid down uponthe gasket and make an airtight joint. The screw thread of the nut -7 isleft hand in this case so that the nut is turned to the right hand inthe direction of the arrow, to force the latch against the under side ofthe head of the stud and force the lid down upon the rubber gasket. Thethread may be made right hand and the nut turned to the left hand ifpreferred, but the way irst described is better as it is a more usualpractice to turn a nut or screw to the right in making it tight.

The fastening is .called a coffin fastening and this is its specialpurpose, but I do not desire to unnecessarily curtail myself in its use,but claim it for any purpose to which it may be properly applied, as afastening for lids, in general.

I claim as my inventionl. The combination in a lid fastening, of aheaded stud projecting upward from the body l and a nut working in ascrew threaded socket ICO of the lid and having an axial bore for thepassage of the stud and a latch engaging beneath the head of the stud,substantiallyr as set forth.

5 2. The combinationin alid fastening, of the body 1 having headed studsand the lid having tubular nuts Screw-threaded in the lid and throughwhich the studs pass and a latch on the nnt engaging beneath the head ofthe ro stud, for the purpose set forth.

. 3. The combination,in a lid fastening, of a body 1 having a headedstud projecting from its upper rim, a nut Working in the lid 8 withaxial bores for the passage of the stud, an arm 15 on the nut adaptedfor use in turning t-he nut
